To all whom it may concern:

Be it known that I, WILLI M. H. WVHITE, a citizen of theUnited States, residing at C olunibus, in the county of Franklin andiitate of Ohio, have invented certain new and useful Improvements in Dough-Raisers, of which the following isa specification.

My invention relates to dough, raiser-s and theobjects of my invention are to provide an improved oyen'l ike structure. adapted to receive and inclose bread dough or sponge and to subject the sponge to a uniform heat for the purposeof causing the spongetd rise prior to the baking thereof; to provide improved-means for directing and distributing the heat from a lamp or other source of heat to the bread dough or sponge containing compartment and to produce other improve. ments the details of which will be more fully pointed out hereinafter. These objects I accomplish in the mannerillustrated in the accompanying drawing, in which- Figure l is a view in perspective of-iny imprin ed bread raising device, Fig.-2-isa central verticah sectionthereof, and, Fig. 3 is a transverse section online w-w of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

l-n'carrying out my inventioiil employ. suitable supporting standards 1, upon which are mounted a box-like casing 2, the forward side of "said casing being provided with a doorway of suitable size; which is adapted to be closed byza hinged door 3, the latter having a. panel of glass or-other transparent materialas indicated at 4. i

5 represents the horizontal bottom plate of the casing and at a suitable distance above this bottom plate, the leasing is provided with a horizontal partition plate 6 which forms a comparatively shallow compartment 7 in the base of the casing'body 2.

. Depending from the underside of the central portion of the partition plate 6 is a conical defiectorp8 which deflectdr is imniediatelyabove an opening 9 in the center of the bottom plate 5. From about this bottom plate 5 there projects downwardly a flaring open-mouthed hood or'conductor 10, such conductor thus extending Within the upper portion of a comparatively small boxli kc casing-11 which depends from the undenside of said bottom plate 5. This'lower and smaller case 11 is provided in its lower ortion with air inlet openings 12 and its other- '2 wit same in an oven, to p wise open outer side is adapted to be closed U by a suitable door13, said door,-'a s provided for. the door 3 having a'transparent-panel 1 L The partition plate G is provided preferably near its marginal portion with verti cal openings 6' and above thepartition plate '6 at desired intervals, I provide within the casing 2, horizontal shelves to which shelves are designed to support the pans of bread dough or sponge which is to be raised.

\jvithin the lower andsmallerdepending casing 11 is intended to be supported a lamp '16, or ,,other suitable heat generating device.

As will readily be understood, the heated air 7 from the lamp is. directed upward through the conductor 10 through the opening 9 and.

8, which tends to spread the heat in all directions from the center of the deflector, thus subjecting the partition plate 6 to a substan, tially uniform heat throughout its surface.

From the compartment 7 the heated air may against the surface of the conical deflector passes through said openings and that which is radiated by the bottom plate 6. I, preferably rovide the upper portionof the casing aplurality of comparatively small outlet openings 17 to insure the proper outlet of the heated air and the production of the proper draft through the casing.

As. is well known it has been customary in raising dough preparatory to baking the acethe pan containing the sponge adjacent toa stove or other heating appliance in order that the sponge may be subjected to a comparatively mild heat, and asis well known, this process of raising the sponge, is not wholly successful owing to the failure to subject the entire mass of sponge-to asteady and uniform heat of the desired temperature, By employing the device which I have herein described, it will readily'be understood that these 'diiiiculties will be overcome and thatthe heating lamp or other device "6 may be so regulated as to insure the maintenance of uniform heat within the casing 2 ancbthe proper raising; of the sponge contained therein its .-From the foregoing description, it 'L'V ll' be seen that-simple and efileientmeans are herein provided for accomplishing the'objects of the invention,- butwhile the elements shown and described :arwell adapted to serve-the purposes for which they are in; tended, it, is to Ive-understood that the ing vention is not limited to the precise construction set forth, but includes Within its purview such changes as may be made within the scope of the appended claim.

\Vhat I claim, is

In a dough raiser, the combination with a supporting frame, a casing mounted on said frame and provided with a shelf, a horizontally disposed perforated partition within the casing below the shelf, a conical deflector depending from the central portion of said horizontal partition, a smaller casingdepending from the bottom of the upper casing and at a point approximately directly beneath the conical deflector, and a flaring conductor arranged beneath the conical deflector and depending from an opening in said upper casing bottom, said conductor having its smaller end adjacent to the conical deflctorvand its widened or flared end generating device in the lower casing.

In testimony whereof I affix my signature '20 extending into the smaller casing, and a heat j
